Huckabee and McCain spoke with reporters Friday on the Straight Talk Express.

(CNN) – Mike Huckabee, a former contender for the Republican Party’s presidential nomination, said it would be “a little bit presumptuous to ever assume” that a congregant agrees with everything a pastor says.

Huckabee, who was a Baptist pastor before eventually becoming Arkansas’s governor, is campaigning with McCain in Little Rock Friday. The former rivals maintained a cordial relationship before Huckabee ended his presidential bid leaving McCain as the GOP’s presumptive nominee.
